The flap wheel is assembled on electric or pneumatic tools and is suitable for polishing stainless steel surfaces, metal chamfers, concave and convex surface treatment, welds, etc., especially in shipbuilding, aviation, large machinery and equipment and other fields.

[0003] Among them, the "adjustable louver wheel that is easy to splice" disclosed in the application number "CN202121515451.0" "includes an adjustable louver wheel, a limited pressure-dividing disk can be detachably installed on the left side of the adjustable louver wheel, and a magnetic connection seat that is fixedly connected to the limited pressure-dividing disk can be detachably installed at the center of the adjustable louver wheel. In the above scheme, the socket is fixedly socketed on the driving end of the pneumatic or electric tool through an octagonal socket groove and four equidistantly distributed locking bolts, and then the adjustable louver wheel is firmly attracted and fixed by using the magnetic conductive card seat at the center of the pressure-dividing disk, three groups of equidistantly distributed limiting cones and the rubidium magnet ring connected to the right side of the truncated table.

The servo motor 103 drives the driving rod 104 to rotate through the second pulley 114, the belt and the first pulley 113.

[0036] Working principle: First, move the semi-annular shell 201 longitudinally, so that the semi-annular shell 201 is supported by the connecting box 101, and the guide groove 202 of the semi-annular shell 201 is in contact with the guide block 106. Move the semi-annular shell 201 transversely, and the semi-annular shell 201 will be supported by the limit block 107.

Similarly, install another semi-annular shell 201.

[0037] Then, the two turntables 307 are rotated in sequence, and the turntable 307 drives the transmission screw 303 to rotate, and the transmission screw 303 drives the cross plate 304, the slide bar 305 and the inferior arc pressure block 306 to move, so that the inferior arc pressure block 306 is inserted into the corresponding two inferior arc grooves 203.

The two semi-annular shells 201 and the two splash-proof shells 204 are sleeved on the outside of the shutter wheel 105, which can block the splashing waste chips and prevent the waste chips from splashing onto the hands of the workers who hold the first anti-slip cover 111 and the second anti-slip cover 112 during grinding, which is safer.

[0038] When the louver wheel 105 needs to be replaced, in order to prevent the semi-annular shell 201 and the splashproof shell 204 from hindering the removal of the bolts, the turntable 307 is rotated in the opposite direction. The reverse rotation of the transmission screw 303 will cause the inferior arc pressure block 306 to disengage from the inferior arc groove 203, and the semi-annular shell 201 and the splashproof shell 204 can be horizontally slid out along the surface of the guide block 106, which is very convenient. By setting up a detachable semi-annular shell 201 and the splashproof shell 204, the difficulty of replacing the louver wheel 105 will not be increased while blocking waste chips.
